In order that the invention may be more' clearly understood reference is made tothe accompanying drawings whereon-the preferred method of carrying out the` invention is illustrated by way of example.

Figure l is a vertical section and Fig. 2 a cross-section through the cash-desk and safety arrangement-f Referring to the drawings: The counter I a is separated from the 'public by a Wall b in which is a Window a. is indicated at d. In-front of the window c is a four-winged rotatable door e surrounded by a cylindrical casing f. The door is only rotatable in the direction of the arrow, and carries at its upper end a toothed ring g prevented from rotating in a direction opposite to the arrow by a pawl g.

As soon as a person enters the compartment IV thefoot-board pressed down under his Weight and the-rod mi is lowered bythe lever 7e until the pin m falls into one of theV holes m2. The revolving door is therebylocked and is prevented from being moved in either direction. The compartment IV is inaccessible Yfrom outside and the person therein can only leave after the cashier, by depressing the lever 7c, has raised -the foot-'board a' and the rod m and thereby withdrawn the I claim n l.
